The Globus concert series 'Büro Siebzig' returns to invite the legendary Senegalese band Ndagga Rhythm Force in collaboration with dub luminary Mark Ernestus. Touring their latest release 'Khadim', Ndagga Rhythm Force returns to the Globus stage with their one of a kind, energetic live show. 'Khadim' is a stunning reconfiguration of the Ndagga Rhythm Force sound. The instrumentation is radically pared down. The guitar is gone; the concatenation of sabars; the drum-kit. Each of the four tracks hones in on just one or two drummers; otherwise the sole recorded element is the singing; everything else is programmed. Synths are dialogically locked into the drumming. Tellingly, Ernestus has reached for his beloved Prophet-5, a signature go-to since Basic Channel days, thirty years ago. Texturally, the sound is more dubwise; prickling with effects. There is a new spaciousness, announced at the start by the ambient sounds of Dakar street-life. At the microphone, Mbene Diatta Seck revels in this new openness: mbalax diva, she feelingly turns each of the four songs into a discrete dramatic episode, using different sets of rhetorical techniques. The music throughout is taut, grooving, complex, like before; but more volatile, intuitive and reaching, with turbulent emotional and spiritual expressivity.
